PRINCETON, N.J., Oct. 27 /PRNewswire/ -- Sandoz Inc. announced today it has initiated a voluntary recall in the US of all 50mg/2mL and 250mg/10mL vials of Sandoz and Parenta brand Methotrexate Injection, USP product ("methotrexate") to the consumer/user level. Consistent with its commitment to quality and patient safety, Sandoz is initiating this voluntary recall of all 24 lots of the affected product following the finding of small glass flakes by Sandoz quality control in a limited number of vials in four lots. The flakes are the result of delamination of the glass used to manufacture the vials of these two dosage presentations.

Due to particle size, there is the potential to develop adverse reactions in areas where the particles lodge. While it is unlikely, parenteral injection of drug from the affected lots could lead to serious adverse events, resulting in disability and death. Additionally, neurologic damage could result from intrathecal administration. Potential adverse events after intravenous administration include local damage to blood vessels in the lung, localized swelling, and granuloma formation. Intramuscular administration could result in foreign-body inflammatory response, with local pain, swelling and possible long term granuloma formation. Intra-arterial administration could result in damage to blood vessels in the distal extremities or organs. To date, Sandoz has not received any adverse event reports or product complaints attributable to particles from any lot of methotrexate, including the lots where flakes have been found.

Methotrexate is an antimetabolite used in the treatment of neoplastic diseases, severe psoriasis, and rheumatoid arthritis, including polyarticular juvenile rheumatoid arthritis. The affected products are only the 50mg/2mL and 250mg/10mL presentations of methotrexate. The product lot numbers, label type and expiration dates are listed below as well as on the Sandoz US website at www.us.sandoz.com.

IMPORTANT SAFETY INFORMATION (PRODUCT LABELING)

WARNINGS

Methotrexate should be used only by physicians whose knowledge and experience include the use of antimetabolite therapy. Because of the possibility of serious toxic reactions (which can be fatal), Methotrexate should be used only in life-threatening neoplastic diseases, or in patients with psoriasis or rheumatoid arthritis with severe, recalcitrant, disabling disease which is not adequately responsive to other forms of therapy.

Deaths have been reported with the use of methotrexate in the treatment of malignancy, psoriasis, and rheumatoid arthritis.

Patients should be closely monitored for bone marrow, liver, lung and kidney toxicities.

Patients should be informed by their physician of the risks involved and be under a physician's care throughout therapy.

The use of methotrexate high dose regimens recommended for osteosarcoma requires meticulous care. High dose regimens for other neoplastic diseases are investigational and a therapeutic advantage has not been established. Methotrexate formulations and diluents containing preservatives must not be used for intrathecal or high dose methotrexate therapy.

Methotrexate has been reported to cause fetal death and/or congenital anomalies. Therefore, it is not recommended for women of childbearing potential unless there is clear medical evidence that the benefits can be expected to outweigh the considered risks. Pregnant women with psoriasis or rheumatoid arthritis should not receive methotrexate.

Unexpectedly severe (sometimes fatal) bone marrow suppression, aplastic anemia, and gastrointestinal toxicity have been reported with concomitant administration of methotrexate (usually in high dosage) along with some nonsteroidal anti-inflammatory drugs (NSAIDs).

Methotrexate causes hepatotoxicity, fibrosis and cirrhosis, but generally only after prolonged use. Acutely, liver enzyme elevations are frequently seen. These are usually transient and asymptomatic, and also do not appear predictive of subsequent hepatic disease. Liver biopsy after sustained use often shows histologic changes, and fibrosis and cirrhosis have been reported; these latter lesions may not be preceded by symptoms or abnormal liver function tests in the psoriasis population. For this reason, periodic liver biopsies are usually recommended for psoriatic patients who are under long term treatment. Persistent abnormalities in liver function tests may precede appearance of fibrosis or cirrhosis in the rheumatoid arthritis population.

Methotrexate-induced lung disease, including acute or chronic interstitial pneumonitis, is a potentially dangerous lesion, which may occur acutely at any time during therapy and has been reported at low doses. It is not always fully reversible and fatalities have been reported. Pulmonary symptoms (especially a dry, nonproductive cough) may require interruption of treatment and careful investigation.

Diarrhea and ulcerative stomatitis require interruption of therapy; otherwise, hemorrhagic enteritis and death from intestinal perforation may occur.

Malignant lymphomas, which may regress following withdrawal of methotrexate, may occur in patients receiving low-dose methotrexate and, thus, may not require cytotoxic treatment. Discontinue methotrexate first and, if the lymphoma does not regress, appropriate treatment sh
